1. Optimal Control of Electric Bus Lines
Abstract : Bus lines are inherently unstable systems, where any delay tends to be further amplified by the accrued passenger loads encountered at stops downstream. This self-reinforcing mechanism, when combined with the multiple sources of disturbances of an urban environment, can lead to the problem of bus bunching. READ MORE

2. Towards sustainable urban transportation : Test, demonstration and development of fuel cell and hybrid-electric buses
Abstract : Several aspects make today’s transport system non-sustainable: • Production, transport and combustion of fossil fuels lead to global and local environmental problems. • Oil dependency in the transport sector may lead to economical and political instability. READ MORE

3. Discrete Event Simulation of Bus Terminals
Abstract : Public transport is important to society as it provides spatial accessibility and reduces congestion and pollution in comparison to other motorized modes. To assure a high-quality service, all parts of the system need to be well-functioning and properly planned. One important aspect for the system's bus terminals is their capacity. READ MORE

4. Regional public transport : The balancing act of service planning
Abstract : This thesis addresses the demand for more knowledge regarding regional public transport (between urban areas or to and from rural areas). More specifically, the aim is to develop a better understanding of the effects of different service planning decisions in terms of different trade-offs and their impacts on the overarching objectives of public transport provision.

5. Impacts of Traffic Signal Control Strategies
Abstract : Traffic signals are very cost effective tools for urban traffic management in urban areas. The number of intersections in Sweden controlled by traffic signals has increased since the seventies, but efforts to study the traffic performance of the employed strategies are still lacking.
